Suzuki GN250 Street Tracker by STG Tracker

Suzuki GN250 Tracker

Argentina has become a hotbed of street tracker and scrambler builds. Much of this interest and energy is thanks to Marcelo Obarrio of STG Tracker. Marcelo, a former cyclist, owned the country’s first brand of freestyle bikes and parts, STG. When he evolved into customizing motorcycles, he kept the same name, opening STG Tracker as a small local workshop. Today, his sister manages the speed shop, allowing Marcelo to concentrate on custom builds.

For quite some time, Marcelo had been wanted to build a street-legal flat track bike. He purchased a 1994 Suzuki GN250 with a damaged engine and went from there, rebuilding the engine with a 300cc big bore kit, adding modern R1 forks, hand-shaping the custom metal tank and tail, and much more.

Below, we get the full story on this street-legal flat tracker.

• Please tell us a bit about yourself, your history with motorcycles, and your workshop.

Hi! I’m Marcelo Obarrio, owner and builder of STG Tracker. STG Tracker started in 2014 when, after modifying my first motorcycle (Suzuki GN250 ‘94) just for fun, I decided to keep on customizing motorcycles. STG was the name of my bicycle’s brand. As a former cyclist, I started designing freestyle bikes and parts in 2006 and was the first Argentinian brand that did that. So since almost ever, I’ve been designing for the two wheels. When I modified the GN250, there were only a few workshops in Argentina. I modified a few bikes and started selling accessories and after a few months I set up my own local shop. It was a small shop where I worked alone modifying the motorcycles and selling accessories. Nowadays I have a local shop where I can work in the customization while my sister manages the speedshop.

• What was the design concept and what influenced the build?

Just keep the race bike essence to the top, but added things as lights to make it a daily driven

• What custom work was done to the bike?

As the engine was not working, basically we rebuilt the engine started from the new crankshaft and a 300cc kit to make it faster. Bigger carb, full inox exhaust. Yamaha R1 front end with double disc/spoked wheel. Adapted a rear disc brake and made in metal the tank and tail, powdercoated frame and it was ready to go.

    love the build. The rear brake line spooks me, paranoid am I. Seems like in a tangle of bikes, another could catch that line and break it, no rear brakes. Maybe that is ok since a tangle that serious is about to come to a stop anyway…..

    More bikes!!!
